As a supreme example of its expertise, all Piaget's watchmaking and jewellery know-how are combined in this exceptional Altiplano model with its record-breaking thickness of only 6.44 mm. Thanks to its sapphire crystal case back this model majestically exhibits its Calibre 1200P, at only 2.35 mm the thinnest self-winding mechanical movement in the world, giving pride of place to its platinum oscillating weight decorated with the Piaget coat-of-arms. The parameters of this unrivalled calibre epitomise the Piaget's restless avant-garde spirit. Matching its technical versatility, its truly dazzling features bring this luxury watch to perfection, emphasising the codes of elegance of the Altiplano Collection. On the dial its slender black baton-shaped hour-markers are thus in marked contrast with the hour-circle with its dazzling baguette-cut diamonds, while the case, its profiles, the horns and even the folding-clasp buckle sparkle with their baguette-cut or brilliant-cut diamonds. The case back is also set with its row of diamonds. In all 260 hours of development and 30 hours of gem-setting were required to create this glittering timepiece ringed with diamonds.

Direct descendant of the legendary 12P movement, the 1200P is the thinnest self-winding mechanical movement in the world. To achieve the record-breaking thinness of 2.35 mm, the watchmaker, Piaget relied on all of its ultra-thin expertise and trimmed down all of the movement's components. Some of the gears in the 1200P have been reduced to only 0.12 mm, hardly thicker than a human hair, and the space between the wheels has been reduced to a minimum of only 0.1 mm. It is also equipped with a balance stop.
In order to make the best use of space, the platinum micro-rotor, decorated with the Piaget coat-of-arms is off-centred and positioned at 9 o'clock on the movement.
As part of Piaget’s constant effort to differentiate its models, it has decorated the wheels of the 1200P movement with a sunburst motif and its index assembly carries the stylised P of Piaget like a secret signature. The circular Côtes de Genève, the circular-grained mainplate, the bevelled bridges, the oscillating weight in platinum engraved with the Piaget coat-of-arms and with its limited edition number as well as the blued screws add the finishing touches to this exceptional movement, while remaining true to the aesthetic codes cherished by the Swiss watchmaking brand.

Piaget was a pioneer in the history of ultra-thin movements, with its famous caliber 9P hand-wound movement and caliber 12P self-winding movement. Both pieces were ranked thinnest in their category worldwide at the time of their launches in 1957 and 1960, respectively.
